The class ``SURF_GPU`` uses some buffers and provides access to it. All buffers can be safely released between function calls.
**Note:**
By default for user provided keypoints the class ``SURF_GPU`` recalculates keypoint's orientation and returns reodered/filtered keypoints array and coresponding decriptors array.

The class ``BruteForceMatcher_GPU`` has an interface similar to the class :c:type:`DescriptorMatcher`. It has two groups of ``match`` methods: for matching descriptors of one image with another image or with an image set. Also, all functions have an alternative: save results to the GPU memory or to the CPU memory. ``Distance`` template parameter is kept for CPU/GPU interfaces similarity. ``BruteForceMatcher_GPU`` supports only the ``L1<float>`` and ``L2<float>`` distance types.
